On 15 September 1935, the Reichstag passed the Nuremberg Laws, prohibiting marriages between Jews and people of Germanic extraction, extramarital relations between Jews and Germans, and the employment of German women under the age of 45 as domestic servants in Jewish households.[12] The Reich Citizenship Law defined as citizens those of "German or kindred blood". Thus Jews and other minorities were stripped of their citizenship.[13] By the start of World War II in 1939, around 250,000 of Germany's 437,000 Jews had emigrated to the United States, Palestine, the United Kingdom, and other countries.[14][15]
Corum continues: General Walther Wever compiled a doctrine known as The Conduct of the Aerial War. This document, which the Luftwaffe adopted, rejected Giulio Douhet's theory of terror bombing. Terror bombing was deemed to be "counter-productive", increasing rather than destroying the enemy's will to resist. Such bombing campaigns were regarded as diversion from the Luftwaffe's main operations; destruction of the enemy armed forces. The bombings of Guernica, Rotterdam and Warsaw were tactical missions in support of military operations and were not intended as strategic terror attacks.[139]
Płaszów concentration camp opened in March 1943 on the former site of two Jewish cemeteries on Jerozilimska Street, about 2.5 kilometres (1.6 mi) from the DEF factory.[49] In charge of the camp was SS-Hauptsturmführer Amon Göth, a sadist who would shoot inmates of the camp at random.[48] Inmates at Płaszów lived in constant fear for their lives.[50] Emilie Schindler called Göth "the most despicable man I have ever met."[51]
Overy wrote that blitzkrieg as a "coherent military and economic concept has proven a difficult strategy to defend in light of the evidence".[127] Milward's theory was contrary to Hitler's and German planners' intentions. The Germans, aware of the errors of the First World War, rejected the concept of organising its economy to fight only a short war. Therefore, focus was given to the development of armament in depth for a long war, instead of armament in breadth for a short war. Hitler claimed that relying on surprise alone was "criminal" and that "we have to prepare for a long war along with surprise attack". During the winter of 1939–40, Hitler demobilised many troops from the army to return as skilled workers to factories because the war would be decided by production, not a quick "Panzer operation".[128]

Once Germany took over Poland in 1939, it created forced-labor camps. Thousands of prisoners died from working conditions, exhaustion, and starvation. After the outbreak of World War II, the number of concentration camps increased exponentially. The number of prisoners of war camps also rose, but after the first years of the war most were converted into concentration camps. Nazis forcibly relocated Jews from ghettos to concentration camps.

Historical accuracy is pushed to the edge as each unit is endowed with the actual capabilities and characteristics that existed at the time. Details such as the thickness of a tank's armor down to the range of infantry rifles add a level of previously unprecedented realism. Each campaign has been meticulously researched to provide an accurate depiction of the battles that took place, while still maintaining the flexibility (and fun!) necessary to let you play the way you want.
These gassing facilities soon proved inadequate for the task of murdering the large numbers of Jewish deportees being sent to Auschwitz. Between March and June 1943, four large crematoria were built within Auschwitz-Birkenau, each with a gas chamber, a disrobing area, and crematory ovens. Gassings ceased at Bunkers I and II when Crematoria II through V began operating, although Bunker II was put back into operation during the deportation of Hungary’s Jews in 1944. Gassing of newly arrived transports ceased at Auschwitz by early November 1944.

Beginning in late 1941, the Germans began mass transports from the ghettoes in Poland to the concentration camps, starting with those people viewed as the least useful: the sick, old and weak and the very young. The first mass gassings began at the camp of Belzec, near Lublin, on March 17, 1942. Five more mass killing centers were built at camps in occupied Poland, including Chelmno, Sobibor, Treblinka, Majdanek and the largest of all, Auschwitz-Birkenau. From 1942 to 1945, Jews were deported to the camps from all over Europe, including German-controlled territory as well as those countries allied with Germany. The heaviest deportations took place during the summer and fall of 1942, when more than 300,000 people were deported from the Warsaw ghetto alone.
The British methods induced "strategic paralysis" among the Ottomans and led to their rapid and complete collapse.[44] In an advance of 65 miles (105 km), captures were estimated to be "at least 25,000 prisoners and 260 guns."[45] Liddell Hart considered that important aspects of the operation were the extent to which Ottoman commanders were denied intelligence on the British preparations for the attack through British air superiority and air attacks on their headquarters and telephone exchanges, which paralyzed attempts to react to the rapidly deteriorating situation.[38]
On 24 December 1941 the resistance groups representing the various prisoner factions met in block 45 and agreed to cooperate. Fleming writes that it has not been possible to track Pilecki's early intelligence from the camp. Pilecki compiled two reports after he escaped in April 1943; the second, Raport W, detailed his life in Auschwitz I and estimated that 1.5 million people, mostly Jews, had been killed.[203] On 1 July 1942, the Polish Fortnightly Review published a report describing Birkenau, writing that "prisoners call this supplementary camp 'Paradisal', presumably because there is only one road, leading to Paradise". Reporting that inmates were being killed "through excessive work, torture and medical means", it noted the gassing of the Soviet prisoners of war and Polish inmates in Auschwitz I in September 1941, the first gassing in the camp. It said: "It is estimated that the Oswiecim camp can accommodate fifteen thousand prisoners, but as they die on a mass scale there is always room for new arrivals."[204]

In April 1940, Rudolph Höss, who become the first commandant, identified the Silesian town of Oswiecim as a possible site for a concentration camp. The function of the camp was initially to intimidate Poles and prevent resistance to German rule. It was also perceived as a cornerstone of the policy to re-colonize Upper Silesia, which had once been a German region, with 'pure Aryans'. On April 27th, Himmler ordered construction of the camp.

The German offensive to capture Stalingrad began in August 1942, using the 6th Army and elements of the 4th Panzer Army. The attack was supported by intensive Luftwaffe bombing that reduced much of the city to rubble. The fighting degenerated into house-to-house fighting; both sides poured reinforcements into the city. By mid-November 1942, the Germans had pushed the Soviet defenders back at great cost into narrow zones along the west bank of the Volga River.
Allied air superiority became a significant hindrance to German operations during the later years of the war. By June 1944 the Western Allies had complete control of the air over the battlefield and their fighter-bomber aircraft were very effective at attacking ground forces. On D-Day the Allies flew 14,500 sorties over the battlefield area alone, not including sorties flown over north-western Europe. Against this on 6 June the Luftwaffe flew some 300 sorties. Though German fighter presence over Normandy increased over the next days and weeks, it never approached the numbers the Allies commanded. Fighter-bomber attacks on German formations made movement during daylight almost impossible. Subsequently, shortages soon developed in food, fuel and ammunition, severely hampering the German defenders. German vehicle crews and even flak units experienced great difficulty moving during daylight.[g] Indeed, the final German offensive operation in the west, Operation Wacht am Rhein, was planned to take place during poor weather to minimize interference by Allied aircraft. Under these conditions it was difficult for German commanders to employ the "armoured idea", if at all.[citation needed]
A parallel system operated later at Birkenau in 1942-43, except that for the majority the 'showers' proved to be gas chambers. Only about 10 percent of Jewish transports were registered, disinfected, shaven and showered in the 'central sauna' before being assigned barracks. In May 1944, a spur line was built right into the camp to accelerate and simplify the handling of the tens of thousands of Hungarian and other Jews deported in the spring and summer of 1944.
Perhaps the most famous orchestra to have come out of Birkenau was the women’s orchestra.  Known through Fania Fénelon’s memoirs and the movie Playing for Time, this group — the only all-women SS-sponsored musical organisation established under Nazi internment — was founded in the spring of 1943.  Originally directed by the Polish inmate Zofia Czajkowska, it reached its peak under the guidance of the violin virtuoso and conductor Alma Rosé.  As with other camp bands, the women were required to play at the gates every morning and evening, to accompany the workers’ arrival and departure from the camp.  This job won them the animosity of many prisoners, who remembered returning to their barracks, sick, exhausted, and often carrying or dragging their dead comrades, while
Auschwitz became one of the camps used for the mass extermination of Jews. In summer 1941, Heinrich Himmler gave orders to Auschwitz commander Rudolf Höß to build a centre at Auschwitz for the mass murder of Jews. In September 1941, the lethal effects of Zyklon B - a substance normally used for pest control - were first tested and verified there. Later, four large gas chambers were built at Birkenau, capable of killing up to six thousand people each day. The gas chambers were disguised as showers, meant to persuade the victims that these were disinfection measures which they had to undergo before they were sent to work in the camp.
Auschwitz was probably chosen to play a central role in the “final solution” because it was located at a railway junction with 44 parallel tracks—rail lines that were used to transport Jews from throughout Europe to their death. Heinrich Himmler, chief of the SS, the Nazi paramilitary corps, ordered the establishment of the first camp, the prison camp, on April 27, 1940, and the first transport of Polish political prisoners arrived on June 14. This small camp, Auschwitz I, was reserved throughout its history for political prisoners, mainly Poles and Germans.
But the personalities and characteristics of human beings cannot be spliced. Sometimes character flaws, such as hubris, also lead to great achievements through a willingness to attempt something most people never would. Oskar’s espionage activities on behalf of Germany, while regrettable to enemies of Germany, later put him in a position to save many lives.
Blitzkrieg   (German, literally lightning war or flash war) is a popular name for an offensive operational-level military doctrine which involves an initial bombardment followed by employment of mobile forces attacking with speed and surprise to prevent an enemy from implementing a coherent defense. The founding principles of these types of operations were developed in the 19th Century by various nations, and adapted in the years after World War I, largely by the German Wehrmacht, to incorporate modern weapons and vehicles as a method to help prevent trench warfare and linear warfare in future conflicts. The first practical implementations of these concepts coupled with modern technology were instituted by the Wehrmacht in the opening battles of World War II. While operations in Poland were rather conventional, subsequent battles — particularly the invasions of France, The Netherlands and initial operations in the Soviet Union — were effective owing to surprise penetrations, general enemy unpreparedness and an inability to react swiftly enough to German offensive operations. That the German Army quickly defeated numerically and technically superior enemies in France led many analysts to believe that a new system of warfare had been invented.
Auschwitz, also known as Auschwitz-Birkenau, opened in 1940 and was the largest of the Nazi concentration and death camps. Located in southern Poland, Auschwitz initially served as a detention center for political prisoners. However, it evolved into a network of camps where Jewish people and other perceived enemies of the Nazi state were exterminated, often in gas chambers, or used as slave labor. Some prisoners were also subjected to barbaric medical experiments led by Josef Mengele (1911-79). During World War II (1939-45), more than 1 million people, by some accounts, lost their lives at Auschwitz. In January 1945, with the Soviet army approaching, Nazi officials ordered the camp abandoned and sent an estimated 60,000 prisoners on a forced march to other locations. When the Soviets entered Auschwitz, they found thousands of emaciated detainees and piles of corpses left behind.
Directive control was a fast and flexible method of command. Rather than receiving an explicit order, a commander would be told of his superior's intent and the role which his unit was to fill in this concept. The exact method of execution was then a matter for the low-level commander to determine as best fit the situation. Staff burden was reduced at the top and spread among commands more knowledgeable about their own situation. In addition, the encouragement of initiative at all levels aided implementation. As a result, significant decisions could be effected quickly and either verbally or with written orders a few pages in length.
In the Lviv pogroms in occupied Poland in July 1941, some 6,000 Polish Jews were murdered in the streets, on top of 3,000 arrests and mass shootings by Einsatzgruppe C.[231][m] During the Jedwabne pogrom, on 10 July 1941, a group of 40 Polish men killed several hundred Jews; around 300 were burned alive in a barn. The attack is thought to have been organized by the German Security Police (Sicherheitsdienst).[233] A long debate about who was responsible for the Jedwabne murders was triggered in 2001 by the publication of Jan T. Gross's book Neighbors: The Destruction of the Jewish Community in Jedwabne, Poland.[234] The response to the book was described as "the most prolonged and far-reaching of any discussion of the Jewish issue in Poland since the Second World War".[235]
After Germany’s loss in WWI, the Treaty of Versailles punished Germany by placing tough restrictions on the country. The treaty made Germany take full responsibility for the war, reduced the extent of German territory, severely limited the size and placement of their armed forces, and forced Germany to pay the allied powers reparations. These restrictions not only increased social unrest but, combined with the start of the Great Depression, collapsed the German economy as inflation rose alongside unemployment.

In July 1943 the Wehrmacht conducted Operation Zitadelle (Citadel) against a salient at Kursk that was heavily defended by Soviet troops.[97][98] Soviet defensive tactics were by now hugely improved, particularly in the use of artillery and air support.[98][99] By April 1943, the Stavka had learned of German intentions through intelligence supplied by front line reconnaissance and Ultra intercepts.[100] In the following months, the Red Army constructed deep defensive belts along the paths of the planned German attack.[101] The Soviets made a concerted effort to disguise their knowledge of German plans and the extent of their own defensive preparations, and the German commanders still hoped to achieve operational surprise when the attack commenced.[102]
The concepts associated with the term blitzkrieg—deep penetrations by armour, large encirclements, and combined arms attacks—were largely dependent upon terrain and weather conditions. Where the ability for rapid movement across "tank country" was not possible, armoured penetrations often were avoided or resulted in failure. Terrain would ideally be flat, firm, unobstructed by natural barriers or fortifications, and interspersed with roads and railways. If it were instead hilly, wooded, marshy, or urban, armour would be vulnerable to infantry in close-quarters combat and unable to break out at full speed.[citation needed] Additionally, units could be halted by mud (thawing along the Eastern Front regularly slowed both sides) or extreme snow. Operation Barbarossa helped confirm that armour effectiveness and the requisite aerial support were dependent on weather and terrain.[68] It should however be noted that the disadvantages of terrain could be nullified if surprise was achieved over the enemy by an attack through areas considered natural obstacles, as occurred during the Battle of France when the German blitzkrieg-style attack went through the Ardennes.[69] Since the French thought the Ardennes unsuitable for massive troop movement, particularly for tanks, they were left with only light defences which were quickly overrun by the Wehrmacht. The Germans quickly advanced through the forest, knocking down the trees the French thought would impede this tactic.[70]

In the 1960s, Alan Milward developed a theory of blitzkrieg economics, that Germany could not fight a long war and chose to avoid comprehensive rearmament and armed in breadth, to win quick victories. Milward described an economy positioned between a full war economy and a peacetime economy.[124][125] The purpose of the blitzkrieg economy was to allow the German people to enjoy high living standards in the event of hostilities and avoid the economic hardships of the First World War.[126]
Between April and June of 1940, Germany invaded Norway, Denmark, the Netherlands, Belgium, and Luxembourg consolidating power across neutral Western Europe. On June 22, 1940, France signed an armistice with Germany, which divided France between the German-occupied territory in the north and the Vichy regime in the south. Although officially neutral, the French state during this time was generally pro-Nazi and cooperated with Germany’s racial policies.
In order to gain a more personal perspective on the film, Spielberg traveled to Poland before principal photography began to interview Holocaust survivors and visit the real-life locations that he planned to portray in the movie. While there, he visited the former Gestapo headquarters on Pomorska Street, Schindler’s actual apartment, and Amon Goeth’s villa.
Initially, Schindler was mostly interested in the money-making potential of the business and hired Jews because they were cheaper than Poles—the wages were set by the occupying Nazi regime.[38] Later he began shielding his workers without regard for cost.[39] The status of his factory as a business essential to the war effort became a decisive factor enabling him to help his Jewish workers. Whenever Schindlerjuden (Schindler Jews) were threatened with deportation, he claimed exemptions for them. He claimed wives, children, and even people with disabilities were necessary mechanics and metalworkers.[39] On one occasion, the Gestapo came to Schindler demanding that he hand over a family that possessed forged identity papers. "Three hours after they walked in," Schindler said, "two drunk Gestapo men reeled out of my office without their prisoners and without the incriminating documents they had demanded."[40]
